EBECRYL® 264

EBECRYL® 264 is an aliphatic urethane triacrylate, primarily used in UV or EB cured products, offering good flexibility, abrasion resistance, and resistance to yellowing. Here's a summary of its key features and specifications:

Introduction:
EBECRYL® 264 is an aliphatic urethane triacrylate diluted with 15% by weight of the reactive diluent 1,6-hexanediol diacrylate (HDDA). It is used in UV or EB cured products, providing flexibility and abrasion resistance.

Performance Highlights:

• Light color
• Low odor
• Fast cure response
• UV/EB cured products exhibit good flexibility, toughness, abrasion, and stain resistance, as well as non-yellowing properties.

Suggested Applications:

• Coatings for wood flooring
• Plastic coatings
• Overprint varnishes
• Screen inks
• Light stable coatings

Specifications:

• Color, Gardner: max. 2
• Appearance: Clear liquid
• Viscosity, 25°C: 37500 - 52500 mPa.s

Typical Physical Properties:

• Density, g/cm³ at 25°C: 1.12
• Functionality, theoretical: 3
• Oligomer, % by weight: 85
• HDDA, % by weight: 15

Typical Cured Properties:

• Tensile strength: 4200 psi (29 MPa)
• Elongation at break: 37%
• Glass transition temperature: 42°C

Viscosity Reduction:
EBECRYL® 264 can be diluted with reactive diluents such as 1,6-hexanediol diacrylate (HDDA), isobornyl acrylate (IBOA), trimethylolpropane triacrylate (TMPTA), and tripropylene glycol diacrylate (TPGDA). Reactive diluents are preferred over non-reactive solvents to reduce solvent emissions.

Storage and Handling:
Avoid exposure to high temperatures, direct sunlight, ignition sources, oxidizing agents, alkalis, or acids, as this may cause uncontrollable polymerization. Store in suitable containers and handle with adequate ventilation. Wash thoroughly after handling. Shelf life should not exceed 2 years.

Precautions:
Refer to the Safety Data Sheet for information on identified hazards and recommended personal protective equipment and procedures. Avoid exposure to high temperatures and ignition sources. Handle with care and use with adequate ventilation.
